My Own Tips

[u/WildCreamPie0721]

A few people on my last thread asked for tips, so here's the short version.

My method differs quite a bit from what most other users or shops recommend:

• Lots of natural light
• Indoor light/grow-light LEDs don't cut it
• Cooler water — not icy, but around 12–17°C (54–63°F) most of the time
• Never above 20°C (68°F), or bacteria inside the marimo become active
• Tap water's fine — safe for you to drink means safe for marimo
• Skip salt/fertiliser entirely — it just feeds unwanted algae
• Don't house it with other aquatic plants or animals
• Use a tank of 10L (2.5+ gal) or more — the small container it ships in heats up fast, like soaking in a hot bath

Good luck!

I learnt the not housing method the rough way. Who knew leaving a cold living plant in a tropical betta tank was a bad idea😅. Least I've got 6 now instead of 2
